24. When the speed of a particle is doubled, the ratioof its kinetic energy to its momentum(a) remains the same(b) gets doubled(c) becomes half(d) of the above

Answer»

it's mometum remain same

yes it gets doubled when two are collision means kenitic energy

Kinetic energy = 1/2 mv^2

Kinetic energy is proportional to square of velocity(or speed)

So when speed is doubled, Kinetic energy becomes 4 times.

yes it gets doubled because speed is directly proportional to K. E

option B is the correct answer

yes it gets doubled in an kinetic energu
